A 54-year-old woman was admitted for mitral valvular repair. After folding plasty to A3, a 30 mm Cosgrove-Edwards ring was placed. There was no mitral regurgitation jet observed by transesophageal echocardiography (TEE) during the operation.

Humanin-mediated inhibition of neuronal cell death, caused by an Alzheimer's disease (AD)-linked mutant gene occurs via binding of Humanin to its heterotrimeric Humanin receptor (htHNR), which results in the activation of the Janus-associated kinases (JAKs) and signal transducer and activator and transcription 3 (STAT3) signaling pathway. A previous study demonstrated that the Humanin-induced activation of the htHNR/JAK2/STAT3 signaling pathway leads to increased expression of SH3 domain-binding protein 5 (SH3BP5), which is an essential effector of Humanin's anti-cell death activity in some cultured neuronal cells.

However, clinical validation is difficult and time-consuming by individual assays or because of very low concentrations at early stages of the diseases. We have developed assay technology through an innovative modification of the immuno-PCR method for the super-sensitive and multiplex detection of target biomarkers.
View Article and Find Full Text PDFHumanin is a secreted bioactive peptide that suppresses cell toxicity caused by a variety of insults. The neuroprotective effect of Humanin against Alzheimer disease (AD)-related death is mediated by the binding of Humanin to its heterotrimeric Humanin receptor composed of ciliary neurotrophic receptor α, WSX-1, and gp130, as well as the activation of intracellular signaling pathways including a JAK2 and STAT3 signaling axis. Despite the elucidation of the signaling pathways by which Humanin mediates its neuroprotection, the transcriptional targets of Humanin that behaves as effectors of Humanin remains undefined.
